Finished run around lake (8)
I believe the answer is:
complete
'finished' is the definition.
(I've seen this before)
'run around lake' is the wordplay.
I cannot quite see how this works, but
'around' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'lake' could be 'l' (geographical abbreviation) and 'l' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for complete that I've seen before include "Bring to a finish" , "Whole, entire, uncut" , "Perfect - finish" , "Done" , "Whole, nothing missing" .)
